P Chidambaram said the fuel price hike increased the burden on consumers

New Delhi: Senior Congress leader P Chidambaram on Monday slammed the government for hiking petrol and diesel prices, saying the recent "interval" was only due to the Karnataka elections which got over on Saturday.

In separate tweets, P Chidambaram also asked all chief ministers to oppose the terms of reference (ToR) of the 15th Finance Commission, which he said was the central government's "attempt to violate the Constitution and wreck the federal system".

"There we go again. More taxes on petrol and diesel, more burden on the consumer. The Karnataka election was only an interval," he tweeted.

In Delhi, the price of petrol was hiked to Rs 74.80 per litre from Rs 74.63 while the rate of diesel was increased to Rs 66.14 a litre from Rs 65.93, according to a price notification issued by state-owned oil marketing companies.

With this, diesel prices have touched a record high while petrol is at a 56-month peak.

Oil PSUs, which had kept rates unchanged for nearly three weeks before Karnataka went to polls despite input cost spiking, reverted to daily revision in prices no sooner had the state voted to elect a new government on Saturday.

Chidambaram also said Kerala Finance Minister TM Thomas Isaac's open letter on the ToR of the 15th Finance Commission deserves support.

"I urge all State CMs and FMs to join hands to protest the Centre's attempt to violate the Constitution and wreck the federal system," he said.

Mr Isaac has said some state finance ministers, who met at Thiruvananthapuram and Amaravati, were worried about the implications of the ToR of the Finance Commission determined by the Union government.

"What the ToR challenge are the federal values enshrined in the Constitution and the modicum of fiscal autonomy State governments enjoy," he has said.
